A population of values has a normal distribution with μ=152.1 and σ= 6.7. You intend to draw a random sample of size n = 25. First calculate z, round it to two (2) decimal places, then use the rounded z-score to determine the required probability accurate to four (4) decimal places. 1. Find the probability that a single randomly selected value is less than 155.5. P(x < 155.5) = 2. Find the probability that a sample of size n = 25 is randomly selected with a mean less than 155.5. P(x < 155.5) =
